Intrinsic safety pan-tilt camera with self-cleaning function

Abstract

The invention relates to the technical field of machinery, electronics, communication and automation, in particular to an intrinsic safety pan-tilt camera with a self-cleaning function. The camera comprises a camera body, and the camera body sequentially comprises a base, a base sealing plate, a bearing supporting plate, a shell sphere and a lower protection ring from top to bottom; an eight-coreconnector is installed on the side wall of the base, multiple pieces of magnetic steel are arranged on the top face of the base, a stepping motor is installed on the upper surface of the base sealingplate in an inverted mode, a conical roller bearing is arranged at the circle center of the bearing supporting plate, a main control panel and a camera are installed on the lower surface of the bearing supporting plate, and a rotating shaft rod penetrates through an inner ring of the conical roller bearing to be fixed to the base sealing plate. An observation window is formed in the surface of theshell sphere, light supplementing lamp panels are symmetrically arranged on the two sides of the observation window, a cleaning cover is installed on the lower protection ring, and a cleaning brush is arranged in the cleaning cover and used for cleaning the camera, the main control panel, the eight-core connector, the stepping motor, the camera and the light supplementing lamp panels.

Description

technical field [0001] The invention relates to the technical fields of machinery, electronics, communication and automation, in particular to an intrinsically safe pan-tilt camera with a self-cleaning function. Background technique [0002] At present, mining cameras are video monitoring equipment for image capture and transmission in important places in underground coal mines, and are suitable for underground coal mines that contain explosive mixed gases such as methane and hydrogen and are at risk of explosion. There are following deficiencies in current mining cameras: [0003] 1. It can only realize directional and static monitoring of the production scene, display a fixed picture, cannot track and monitor moving objects, and cannot track the moving coal shearer and hydraulic support in all directions, and the information acquisition is relatively one-sided; [0004] 2. For some underground scenes with large mining height and insufficient light, the video clarity is in...

AI Technical Summary

Problems solved by technology

[0003] 1. It can only realize directional and static monitoring of the production scene, display a fixed picture, cannot track and monitor moving objects, and cannot track moving coal shearers and hydraulic supports in all directions, and the information acquisition is relatively one-sided;

[0004] 2. For some underground scenes with large mining height and insufficient light, the video clarity is insufficient and the image quality is poor;

[0005] 3. In a coal mine with large ash and humidity, the lens is easily polluted, and it is impossible to track the entire process of coal mining, and it is impossible to continuously obtain accurate information. Manual cleaning is required, which is time-consuming and laborious;

[0006] 4. Unable to meet the future technical needs of unmanned mining
